  • Patent number: 7825667
    Abstract: A microwave imaging process, and a system controlled by an associated software product, illuminate a target with microwaves from a transmitting antenna. Receiving antennas receive microwaves scattered by the target, and form microwave data. The illumination and receiving repeat over multiple transmitting antennas and multiple microwave frequencies. The microwave data is processed to form permittivity and conductivity images by selecting a background dispersion model for permittivity and conductivity. Permittivity and conductivity dispersion coefficients are determined, and permittivity and conductivity distributions are calculated, for each of the microwave frequencies. Forward solutions at multiple frequencies are determined from property distributions, and a dispersion coefficient based Jacobian matrix is determined. Dispersion coefficient updates are determined using the microwave data, and the dispersion coefficients are updated.

  • Patent number: 7808451
    Abstract: An organic electroluminescent display device connected by a blocking diode in series to an organic light-emitting diode (OLED). Each pixel or subpixel of the electroluminescent display device comprises an OLED, a blocking diode to prevent the OLED from being reversed biased, a rectification diode to isolate the column electrode from unselected rows and a capacitor as a memory device. The charge stored in each memory capacitor may be increased by the blocking diode in series with each OLED. A frame period of the display device is divided into sub-frames that have address and light emission periods. Current mode data programming is used to address the device in each sub-frame. A ramp waveform is applied to the row electrode during the light emission period, to cause the capacitor to discharge through the OLED and control the forward current level.

  • Patent number: 7755010
    Abstract: A non-invasive microwave analysis method determines scattered phase and/or amplitude data for a liquid in a container. A transmitter antenna transmits microwaves that scatter from the container and the liquid in the container. One or more receiver antennas convert the microwaves into microwave electronic signals that are processed to determine the scattered phase and/or amplitude data. Another non-invasive microwave screening method includes placing a container of an unknown liquid in a tank. The container is separated by a membrane from coupling liquid in the tank. Microwave radiation transmits from a transmitter antenna and scatters from the container and the unknown liquid. One or more receiver antennas convert the microwave radiation into microwave electronic signals. The microwave electronic signals are processed to determine scattered phase and/or amplitude data. A pass result or a fail result is determined based on the scattered phase and/or amplitude data.
